with an inlet opening I provided with a nipple 8 for connection with a supply pipe 9. At its upper end this header is open and is provided with screw cap HJ having a central opening ll. Outlet opening I is provided at its upper end within the header with a valve seat l2 to receive valve'l3 which is carried by valve stem 'l4. .This valve stem l4 may extend upward through opening II in screw cap 10 and be provided at its'upper end with a hand wheel I5 or other means for operatingit. But in the construction shown the valve stem terminates within the header, being screw threaded at I6 at its upper end to receive screw threaded sleeve I! which is provided above the screw threaded portion with a shoulder l8 to fit against a recess [9 in the inner face of screw cap l0, and extends at reduced diameter upward through opening ll of the screw cap and is provided above the screw cap with hand A coiled spring 20 between the hand wheel and the screw cap holds the shoulder 18 against recess l9. By rotating hand wheel IS the distance of valve I 3 from valve seat I2 may be regulated to control admission of the heating medium from supply 'pipe 9.

The valve stem I4 is provided with ashoulder 2| on which is secured the lower end of a bellows 23 to the upper end of which is secured a plate 24 which in turn, is held tight against the upper end of header 3 by screw cap ID, the purpose of the bellows being to permit the lower end 22 of the bellows to move with valve .l3 toward or away from valve seat I2 while plate 24 at its upper end is so held between the upper end of the header and screw cap l0 as to prevent any leakage from the interior of theheader past the valve operating mechanism. While one form of valve of the socalled packless type is shown it should be understood that the invention is not restricted to the particular form or type of valve shown as other valves, either packed, or packless or automatic, may be used. I l

The wall of header 3 is open towards the radiator tube or tubes 5. Header 4 is closed towards the radiator tube or tubes 5. Header 4 is closed towards the radiator tube or tubes except for a small opening 24 near its lower end to shield the bellows from contact with steam. At its lower end header 4 has an opening 25 from which extends downward nipple 26 for connection with '30 extends upward to a disc 3| at the lower end of bellows 32 which carries at its upper end disc 33 from which extends upward, in line with the valve stem 30 a stem 24, the upper end of which is screwed in screw-threaded plug 35 in the upper end of the header.' An air vent 38 is con-' v veniently located within the upper part of the chamber 4 and preferably within the screw cap 35. It may be manually operated, as shown in Fig. 1, or of the automatictype. The air within the chamber 4' is expelled through the vent when the heating medium is introduced into the radiator, in order to allow the heating medium to be permitted to enter the chamber above the opening '24. The expansion or contraction of the bellows 32 by change in the temperature within header 4 lifts or depresses the conical end 29 of valve stem 30 toward or from valve seat 28.

The headers 3 and 4 are preferably of cast metal and are of such diameter as to provide for receiving Within them the inlet and outlet valves and are provided on the sides towards each other with suitable sockets in which the radiator tubeor tubes 5 may be secured, and may be constructed to carry one, two or more radiator tubes or series of tubes.

While the construction shown is particularly adapted for use with a so-calledtwo pipe steam, 1

vacuum or vapor system, the substitution for the valve and controlling means (parts 28 and-34) shown, of suitable commercial type of air valve would adapt the radiator for use in a one pipe steam or hot water system.

In the construction shown radiator tube 5 is a flat tube having its vertical dimension much greater than its thickness but instead of this single' tube a plurality of tubes cylindrical or. of other shape or a series of sections or loops or other form in cross section may be used.

Having thus described my invention what I ing the size of the said outlet opening located within said header, the said tubes being closed at their outlet ends by said header except for a small opening adjacent the lower side thereof, which is open to the outlet header, a valve associated with the inlet header for controlling the admission of heating medium to the inlet header.

2. A radiator for conveying a heat exchange medium having an inlet header at one end and a plurality of cylindrical horizontal radiation tubes arranged in parallel in' open communication" therewith, an outlet header'at the opposite ends of the radiation tubes provided with an outlet opening, an automatic control valve for varying l the size of the said outlet opening located in said header, the said tubes being closed at their outlet ends by said header except for small openings adjacent the lower sides thereof, which are open 7 to the outlet header, a valve associated with the inlet header for controlling the admission of heat ing medium to the inlet header. 1
